Use when a collection needs queried or joined test inputs, a reusable named view, spreadsheet worksheet data, live database rows, or script access through pm.datasets(). Chooses between a simple iteration file and a dataset while preserving query semantics, portability, and credential boundaries. Use for requests such as "run this collection over database rows".
